I was disappointing finding out that this shampoo consists Hydrogen peroxide. The amount is probably harmless ,but nevertheless don&#39;t feel like using it on my kids. Just tried it on myself- the scalp turned red a bit ,but isn&#39;t itchy. The hair looks lighter from the first use, but I am the only one who can see the result.

And I've tried just about all of them. My darkening natural blonde hair responds to peroxide bleach in the right amount. This product has it.
This type of bleach is the most commonly used to lift the dark from naturally blonde hair. Because it's bleach it will eventually dry the hair, I mix it with my regular shampoo and use a good conditioner.
The results are subtle, but they're there. I expect after repeated use and time in the sun will lighten my hair to the degree that I want. I prefer the gradual approach. I find this product an excellent alternative to salon highlights.
I've had more disasters than successes with hair color kits and other spray bleach-based products for blonde hair so this product is a real find for me.
